Last December, Toshiba announced a new range of SSD using MLC Flash NAND engraved at 43nm and with a maximum capacity of 512 GB. After some delay with mass production only beginning in the second quarter, Toshiba has announced the imminent delivery of these new SSDs.

The 2.5" versions have been announced with 64, 128, 256 and 512 GB capacities and the 1.8" versions with 64, 128 and 256 GB capacities. Read speeds have been announced at 230 MB/s and writes at 180 MB/s and from what we can see Toshiba are using a proprietary controller. Does this mean new competition for Indilinx, Intel and Samsung? A fourth decent MLC solution?
